What do tiny spiders feed on?

The past few days I have been accompanied on my commute to work by a spider the size of a nail head. It is suspended from the windshield by a thread. I do not know what it is up to. It has not started spinning a web, though it is rather agile going up and down on the thread.

It got me to wondering what spiders this size and smaller feed on. Do they spin webs that can catch much larger insects? This spider would be able to dine on a housefly for a considerable amount of time.

I don’t imagine it is going to find anything in my car. I should probably repatriate it to the great outdoors, taking care not to squish it in the process.

Being a spider, it can ensnare something in its web bigger than itself and can bite it, inject venom to paralyze it and wait til it either exhausts itself first, struggling to escape the web then have a delicious meal. It’s a wrap. lol
Something like a baby jumping spider would rely on tiny gnats or other smaller insects it could pounce on.

@Coloma , I thought of that and I wonder if it works out that way. Even if an insect is ensnared in the web, it can still fight back. Maybe the spider has to wait until the insect weakens sufficiently or dies from starvation.

@LostInParadise I think so, wait until it is exhausted then pounce.
Dying of starvation though would defeat the purpose because the spider needs a juicy fresh bug with lots of body fluids so it can suck the life out of it. haha
